Los Angeles’s aerospace suburbs no longer have many aerospace companies or workers in them, but their legacy—a geographical division of labor, class, and race reflected in and reinforced by corporate planning—continues to shape the region’s suburban landscape. In the early 1960s, aerospace companies relocated their new divisions to the emerging edge cities of greater Los Angeles. Until the end of the Cold War, these “blue-sky” suburbs—white, white-collar, and with predominantly male workforces—reinterpreted the California dream for an upper-middle class who believed they had little in common with their blue-collar counterparts left behind in older working-class communities.

This study of wage bargaining in the aerospace industry focuses particularly on lump sum bonuses, one-time cash disbursements that generally accompany lower increases in the base wage than were formerly standard. Although such bonuses, which appeared in aerospace companies before they appeared in other large manufacturing industries, were viewed as a union concession, they persisted into the 1989 bargaining round despite a sharp upturn in the fortunes of the most prominent aerospace company. The author regards that fact, as well as the weakening of both inter- and intra-industry pattern bargaining, as support for the view that a significant shift in union wage determination occurred in the 1980s. He argues, however, based on interviews with managers, union officials, and workers, that consensus has not yet been achieved on the meaning of this shift.

Abstract The riveting parameters strongly affect residual stresses induced during riveting, which in turn have an impact on the fatigue life of riveted joints. Since rivets are established as critical from the fatigue point of view, the fatigue life of riveted joints often determines the life of the whole structure. The authors were able to become acquainted with three riveting instructions (process specifications) used by the aerospace companies from western Europe. This work presents the analysis of the riveting parameters' influence on residual stresses around the rivets. The impact of the clearance between a rivet shank and a hole as well as driven head dimensions and a rivet length were investigated based on the numerical simulations. The aim of the analysis was to determine the range of stresses variation when the requirements of the riveting instructions are fulfilled. For the purposes of comparison, the calculations were performed also with the parameters as specified in the Polish industry standards. For all calculations, the geometry of the universal rivet MS20470 was used. The results show that residual stresses can vary strongly depending on the parameters in the instructions and standard requirements.
